[0002] The primary function of a battery tab is to establish an electrical connection between the battery's internal electrodes and the external circuit. Tabs are typically made of metal materials, such as copper (for the negative electrode) or aluminum (for the positive electrode), which have excellent conductivity and mechanical properties. In soft-pack batteries, tab glue is responsible for sealing the tab to the battery casing (aluminum-plastic film) to prevent electrolyte leakage and external moisture intrusion. Tab glue also secures the tab, ensuring a secure and reliable connection between the tab and the battery's internal electrodes.
[0003] The existing tab glue requires precise positioning to ensure that the tab glue can be correctly heat-sealed with the aluminum-plastic film. However, when manual gluing is used, the positioning of the tab glue film is not stable enough, and the gluing of the tab glue usually depends on the proficiency of manual operation. If the tab glue is crooked, it needs to be adjusted, which is time-consuming. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-4The utility model provides a technical solution: a positioning structure for a tab and tab glue, comprising a tab glue positioning structure body 1 and a battery tab 11, a tab glue positioning structure body 1 provided with a glue sticking platform 2 and a tab glue roll fixing seat 5, and a tab glue roll 6 is clamped and installed in the tab glue roll fixing seat 5, a clamping strip 7 is integrally provided on the side of the tab glue fixing seat 5, and the clamping strip 7 is movably clamped with the side of the tab glue sticking platform 2, a strip-shaped through hole is opened on the side of the tab glue sticking platform 2 close to the positioning frame 10, and an end positioning plate 14 is longitudinally movably clamped in the through hole of the tab glue sticking platform 2, this structure allows the end positioning plate 14 to move up and down relative to the tab glue sticking platform 2, and a spring is clamped and fixed on the bottom of the end positioning plate 14 The spring connector 15, and the right end of the tab film 6 is aligned with the left surface above the end positioning plate 14. This structure can position the end of the battery tab 11 through the end positioning plate 14, so that the right side of the tab film 6 is aligned with the side of the battery tab 11, ensuring the precise positioning of the tab glue. The spring connector 15 can allow the end positioning plate 14 to be reset after moving down. The cross-section of the end positioning plate 14 is an inverted T-shaped structure, and the upper end of the end positioning plate 14 is an arc surface. Because the positioning frame 10 can be rotated under the positioning of the connecting seat 12, this structure makes it possible for the positioning frame 10 to be rotated to the glue sticking table 2 and be horizontally set. After that, the positioning frame 10 can press the end positioning plate 14 into the glue sticking table 2. At this time, the positioning frame 10 frames the part of the battery tab 11 that needs to be glued. After the manual gluing is completed, the tab glue can be cut through the tab film fixing seat 5. One end of the gluing platform 2 is symmetrically provided with a connecting seat 12, and the connecting seat 12 is connected to the positioning frame 10 with a square frame structure by rotating the rotating shaft. The end of the positioning frame 10 away from the tab film fixing seat 5 is fixed with a U-shaped handle 3 by screws, and a strip through hole is provided on the side of the long side of the positioning frame 10 close to the connecting seat 12. This structure can rotate and adjust the positioning frame 10 through the handle 3. The positioning frame 10 is close to the end of the tab film fixing seat 5 with grooves parallel to each other, and one of the grooves of the positioning frame 10 is clamped in place. It is equipped with a cutting knife 9, and a movable plate 4 is movably engaged in the strip-shaped through hole of the positioning frame 10, and a sponge 13 is bonded and fixed to the bottom of the movable plate 4, and the sponge 13 is in contact with the glue-sticking platform 2. This structure allows the movable plate 4 to move on the glue-sticking platform 2, so that after the battery pole ear 11 is affixed with the pole ear glue, the sponge 13 pushes the pole ear glue to achieve the fitting operation of the pole ear glue, and the positioning frame 10 is clamped in another groove with a pole ear glue limiting rod 8 symmetrically arranged with respect to the pole ear film 6, and the pole ear glue limiting rod 8 can be used to limit the pole ear glue to assist in pulling out the pole ear glue for glue-sticking. The battery pole ear 11 is placed on the glue-sticking platform 2, and the battery pole ear 11 corresponds to the position of the pole ear film 6.
[0019] Working principle: When using the positioning structure of the tab and tab glue, first place the battery tab 11 on the glue sticking platform 2 of the tab glue positioning structure body 1, and align and position the end of the battery tab 11 through the end positioning plate 14, and then use the handle 3 to rotate the positioning frame 10 relative to the glue sticking platform 2 under the positioning of the connecting seat 12 until the positioning frame 10 is horizontal on the glue sticking platform 2. At this time, the positioning frame 10 presses the end positioning plate 14 into the glue sticking platform 2, and the spring connector 15 fixes the bottom of the end positioning plate 14 so that the end positioning plate 14 can be reset after the positioning frame 10 is withdrawn.
